Level control
Telligent® level control (NR)
You can raise or lower the chassis to pick up or offload interchangeable platforms, semitrailers or containers.
 | Risk of accident |
|
If the chassis is in the raised position and you do not observe maximum headroom notices when driving through underpasses, there is a danger of the vehicle being damaged.
Make sure that the permissible height limit is not exceeded when the suspension is raised. In Germany, for instance, maximum vehicle height must not exceed 4 m. Observe the respective national legislation when the vehicle is operated in other countries or when it is used in international transportation.
If the chassis is in the lowered position, there is a danger of the vehicle being damaged because of, amongst other things, insufficient spring travel and ground clearance.
The vehicle’s handling and braking characteristics may change when driving the vehicle with the chassis frame above or below the normal position (driving position).
Drive your vehicle in the normal position (driving position) whenever possible.

| Risk of injury |
|
If the control unit for Telligent® level control is not correctly fitted in the bracket designed for this purpose, there is a risk of injury when leaving the cab. You could get caught and trip up on the control unit connecting cable.
Therefore, always place the control unit in its bracket, with its connecting cable pointing towards the rear of the cab.
|
Vehicles with an air-sprung rear axle: the chassis can only be raised or lowered at the rear axle.
On fully air-sprung vehicles: the chassis can be raised or lowered at the front or rear axle.
If the charge pressure in the compressed-air system is too low:
| |
Run the engine.
|
| |
The compressed-air system is charged.
|
If the vehicle key is in the drive position in the ignition lock, the height of the chassis is adjusted automatically.
A malfunction in Telligent® level control is shown in the display.

Raising/lowering the chassis
Storing the chassis height
Buttons M1 and M2 can each be used to store and select a chassis height.
Calling up the stored height of the chassis
Press M1 button or M2 button to call up the respective stored height of the chassis.
Loading and unloading the vehicle
You can store a constant chassis height for loading and unloading the vehicle.
If there is sufficient reservoir pressure in the compressed-air system, the stored height of the chassis is kept constant for approximately 4 to 5 hours.
 | |
|
Before interchangeable platforms or containers are offloaded, lower the chassis frame completely. Otherwise, the chassis could rebound suddenly when the special-purpose body is offloaded. This could damage the shock absorbers.
|
Normal position (travel position)
If you wish to continue the journey after the chassis height has been modified, the chassis must be set to the normal position (driving position).
Vehicles for the transportation of bulk cargo - raised travel position
To improve ride comfort, you can raise the chassis while the vehicle is in motion.
